Doubling which quantity would cause the largest increase in a spring’s elastic potential energy?
displacement
spring constant
mass
gravitational acceleration

Answer : Doubling displacement would cause the largest increase in a spring’s elastic potential energy.

Explanation :

The work done in stretching a spring is called elastic potential energy.

Where,

k is the spring constant.

x is the displacement.

So, elastic potential energy is directly proportional to the displacement.

So, doubling the displacement would increase its elastic potential energy by a factor of 4.

Hence, the correct option is (A) " displacement ".

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
